Let's say I have a table MyTable with two colums, One and Two. If I wanted to return unique combinations of these two fields I can do
select distict One, Two from MyTable
How do I return the count of such unique combinations? The following of course does not work but you get the idea.
select count(distinct One, Two) from MyTable
Thanks.
I want to start with a table that has 4 records:
-Self
-Supervisor
-Peer
-Direct Rep
And I want to end with a table that has every unique combination of these records (the order being reversed would be considered 'unique' in this context)
-Self , Supervisor
-Supervisor , Self
-Self , Peer
-Peer , Self
-Self , Direct Rep
-Direct Rep , Self
-Peer , Direct Rep
-Direct Rep, Peer
How would I do this in an SQL Query? Thanks for your help!
how to find all possible combinations of values, for example:
My table includes:
Code:
CREATE TABLE temp1 (item varchar(50), ORDER int);
INSERT INTO temp1 (item, order) VALUES ('apple',1);
INSERT INTO temp1 (item, order) VALUES ('pear',2);
INSERT INTO temp1 (item, order) VALUES ('blueberry',3);
I need the output to be like this:
apple
pear
blueberry
apple, pear
apple, blueberry
pear, blueberry
apple, pear, blueberry
I don't need the reverse of each. For example, I need only 'apple, pear'... I don't need 'pear, apple'.

I've got the following query
SELECT MAX(CountCategories.countOfCategory) AS maxCategory, CountCategories.phoneNumber, CountCategories.category
FROM
(SELECT Categories.phoneNumber, Categories.category, Count(Categories.category) AS CountOfcategory
FROM Categories
GROUP BY Categories.phoneNumber, Categories.category) AS CountCategories
GROUP BY CountCategories.phoneNumber, CountCategories.category;
As you can see I have a sub query that is counting categories for the same phoneNumber and category. I then create a Select query about this as I wanted to only return the highest result. However the above query is returning the same as the subquery.It isn't showing me the unique result for the highest count.
I have a table in Access 2007 that has about 30 field names and I want to have a count of how many unique rows there are in each field. I want to have these results put into another table that will just have the field name and then the count of how many unique rows there are.
I have code in VBA that will loop through my SQL and change out the field name, but I can't seem to get the SQL right before I can start looping it. For just one field name this would be what I have to count the unique names...
So far I have this:
INSERT INTO newtable
COUNT(*) FROM (SELECT Raw_Table.FieldName, COUNT(Raw_Table.FieldName) AS CountOfFieldName
FROM Raw_Table
GROUP BY Raw_Table.FieldName);
And its not going too well.
I need a query to return two values. One will be the total units and the other will be total unique units. See exmaple data below. It does not have to be one query. This will be in SP, so I can keep it seperate if I have to.
ID | ID_UNIT
1 | 01
1 | 01
1 | 02
1 | 03
1 | 03
1 | 04
1 | 04
I need two results.
Total Units = 7 - easy to do by using count()
Total unique units = 4 - I cannot use group by as it would return multiple results for each unit, which is not what we want.
Aim- Need to count how many [FDMSAccountNo] fall under a unique parentid
This is my query
SELECT [FDMSAccountNo]
,ParentID
FROM [FDMS].[dbo].[Dim_Outlet]
where ParentID = '878028271889'
Which produces the following, The number of fdmsaccountno under parentid is two. Its two because one of the fdmsaccountno is = to parentid
FDMSAccountNo ParentID
878028271889878028271889
878028272887878028271889
878028273885878028271889
Desired result
Parentid #_of_outlets
878028271889 2
Ok... I know this is something that I've seen and probably done before....
I have a value that will show up multiple times in a table. I want to order the table by that value and then count up from 1 to however many items that it shows up as.

Can some one give me a generalized query for this problem?
Thanks,

I was using the code in this thread (http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=1371094&SiteID=1) to create a console application which can build the SSIS package dynamically and run the package.
I'm not clear on what all could be the possible key / value combinations for the SetComponentProperty Method. From the examples I have seen its either SqlCommand or OpenRowSet. But I'm not sure about the "AccessMode" with values either 0 or 2. Is there any reference where I get more information on these?

The requirement in to write a query which will return top 2 rows (in terms of lst_updt_timestamp column) for every combinations of cust_alias_nm, carrier_cd, acct_nbr columns.
Here I wrote a query which selects top 1 only.
Please help me to write to get the top 2nd along with the top 1st row.
select A.cust_alias_nm_id,
A.carrier_cd_id, A.acct_nbr_id,
sum(A.pd_clm_amt) clm_amt,
sum(A.pd_med_amt) med_amt,
sum(A.pd_exp_amt) exp_amt,
A.lst_updt_timestamp
from bal_load_stg A
group by A.cust_alias_nm_id, A.carrier_cd_id, A.acct_nbr_id, A.lst_updt_timestamp
having A.lst_updt_timestamp
in (
(select max(lst_updt_timestamp) from bal_load_stg B
where
A.cust_alias_nm_id = B.cust_alias_nm_id
and A.carrier_cd_id = B.carrier_cd_id
and A.acct_nbr_id = B.acct_nbr_id))
The output looks like:

I am quite new in sql. I am writing a report which takes data of one same column and summing them according to the type as described in another column("TR_1"."TTYPE"). So far I have succeeded to get the sum of only one type at a time (by putting WHERE "TR_1"."TTYPE" = or not equal the desired type). For example: I want to create two columns, one showing the sum of the budget and the other the some of the actuals: here is my SQL instruction (the column "TR_1"."TTYPE" give the record type):
******************************************************************
SELECT SUM("TR_1"."AmountLCU")*-1 "Budget",rtrim("TR_1"."COSTCENTER") "Cost Centre",rtrim("TR_1"."ACCOUNT") "Account Num",rtrim("TR_1"."DONOR") "Donor Num", "TR_1"."AmountLCU"*-1 "Amount","TR_1"."TTYPE", rtrim("TR_1"."ACTIVITY") "Activity Code" FROM "scalaDB"."dbo"."A_GL0601_PREVIOUS" "TR_1"
WHERE NOT ("TR_1"."TTYPE"='' OR "TR_1"."TTYPE"='a' OR "TR_1"."TTYPE"='c') AND NOT ("TR_1"."COSTCENTER"=N'' OR "TR_1"."COSTCENTER"=N'0000') AND (("TR_1"."ACCOUNT">=N'26' AND "TR_1"."ACCOUNT"<N'7100') OR ("TR_1"."ACCOUNT">N'7100' AND "TR_1"."ACCOUNT"<=N'7999'))
GROUP BY "TR_1"."COSTCENTER","TR_1"."ACCOUNT","TR_1"."DONOR","TR_1"."ACTIVITY","TR_1"."AmountLCU","TR_1"."TTYPE"
**********************************************************************
Note: the report is written in Crystal reports and the database is SQL Server (not sure of the version)
Thanks in advance

How would I write a query to produce all combinations for a situation such as the following?
Suppose I wanted to write a sentence, "This is [adjective] [noun]." where [adjective] comes from the Adjective table and [noun] come from the Noun table.
Adjective table looks like e.g.
ID Adj
1 good
2 so so
3 bad
Noun table looks like e.g.
ID Noun
1 apple
2 orange
3 banana
And the result set would look like
This is good apple.
This is so so apple.
This is bad apple.
This is good orange.
This is so so orange.
This is bad orange.
This is good banana.
This is so so banana.
This is bad banana.
I would take a stab at this myself and post even something that doesn't work...
We need to store land title information about properties in variousAustralian states, but each state maintains it's own land titleregistry and use different columns (well actually differentcombinations of the same columns). For example:Victoria store:TorrensUnitTorrensVolumeTorrensFolioQueensland store:TorrensCountyTorrensLotTorrensPlanTorrensParishTorrensUnitTorrensVolumeTorrensTitleRefThere are 11 different columns and they are used in 8 differentcombinations depending on the state.Since we need to store information about land in different states I seetwo possible solutions:1. A sparse table containing the 11 columns with a CHECK constraint toenforce the valid combinations.2. A table for each state containing only the columns relevant to thestate with a foreign key relationship to the table containing thecommon columns.I'm not sure if the data type and length is consistent between statesyet (waiting to find this out) but assuming that it is which of theseapproaches is going to be the most rigorous? I'm leaning towards (2)but I don't like the feel of a table per state.
View 4 Replies View RelatedI need a function or a routine in sql for making all possible combinations of strings with given letters.
means if I give a string 'ab' the function should return
'a,b,ab,ba' if we give 'abc' it should return 'a,b,c,ab,ac,ba,bc,ca,cb,abc,acb,bac,bca,cab,cba'.
return data can be a single list or the list elements can be printed to screen one by one.

I need to populate a table which have 10 columns with four values. Each row should be a different combination of these four values and the columns can be null too. In other words how can I get all the different combinations for the 4 values that can be in 10 buckets. The final result column based on these values will be generated manually.
For example , I have for grades (P,F, WP, WF) and I have 8 terms and two exams. 8 terms and two exams can have any of the above four values. Based on these grades and terms and exams I need to generate a table which wil be used to determine the student final status Pass/Fail.
What will be the best way to do this and how is it possible. Is there a T-SQL or C# program for this.
If I need to submit this in another forum please let me know.
I have developed an ASP.NET form with 12 different fields that will allow end users the cability to query 3 tables that are relational to one another.
I was curious what is the best way to perform this in a Stored Procedure?

or account for evey kind of WHERE clause based off IF statements on the data that is passed through the parameters?

A UNIQUE INDEX must inherently impose a unique constraint and a UNIQUE CONSTRAINT is most likely implemented via a UNIQUE INDEX. So what is the difference? When you create in Enterprise Manager you must select one or the other.

Hi everyone,
I need urgent help to resolve this issue...
As far as the performance goes which one is better..
Unique Index(col1, col2) OR Unique constraint(col1, col2) ?
Unique constraint automatically adds a unique index
and unique index takes care of uniqueness then whats the use of unique constraint ?
Which one do one use ?
thanks

BOL says a unique constraint is preferred over a unique index. It also states that a unique constraint creates a unique index. What then is the difference between the two, and why is a constraint preferred over the index?

.Can i create umique constraint with out unique index.when i am creating a unique constraint sql creates a unique index (default) can i have only unique constraint ?
I am having a problem trying to figure out the best way to get the results I need. I have a table of part numbers that is joined with a table of notes. The table of notes is specific to the part number and user. A row in the notes table is only created if the user has entered notes on that part number. I need to create a search that grabs all matches on a keyword and returns the records. The problem is that it currently returns a row from the parts table with no notes and a separate row with the notes included if they had created an entry. It seems like this should be easy but it eludes me today.
Here is the code
Code Snippet
create procedure SearchPartKeyword
(
@Keyword varchar(250) = null,
@Universal_Id varchar(10) = null
)
as
select p.PartNumber, p.Description, p.ServiceOrderable, n.MyNotes, p.LargestAssembly, p.DMM,
p.Legacy, p.Folder, p.Printer
from Parts p inner join notes n on p.PartNumber = n.Identifier
where n.Universal_ID = @Universal_ID and p.Description like @Keyword
union
select p.PartNumber, p.Description, p.ServiceOrderable, '' as MyNotes, p.LargestAssembly,
p.DMM, p.Legacy, p.Folder, p.Printer
from Parts p
where p.Description like @Keyword
and the results:
PartNo Description SO Notes LA DMM Legacy Folder Printer
de90008 MAIN BOARD 1 DGF1 114688 0 0 0
de90008 MAIN BOARD 1 I love this part Really I do DGF1 114688 0 0 0
This could return multiple part numbers and If they have entered notes I want the row with the notes
Thank You
